Security worker helps schoolgirls who saw it happen

David Huggins was outside at the time it happened, just before 9pm.

“I’m security at one of the cultural events. I saw the ambulance pull up really sharply and they have gone running in with the police. Princes Quay has been evacuated completely and all are still on site.

“We had to take four schoolgirls in who had seen it apparently and wait for their parents. They were shook up.

“We have heard a guy fell off the first or second floor. Apparently he has died.”

Man describes scene outside Princes Quay

“I was just walking home as I live in Old Town. As I was approaching the entrance to Princes Quay I could see two police cars, one police van and one first respond ambulance car. Another police car was to the right.

“There was no police outside the entrance so I would assume they were inside somewhere. As I started to walk past, heading towards Whitefriargate, I could see a few members of the public stood at the metal fencing looking towards the Quay. That’s when I could see more police and ambulance vehicles parked on the bridge entrance to Princes Quay.

“I didn’t stick around as I needed to get home but one can only guess with that amount of ambulance vehicles someone may have injured themselves inside Princess Quay. Again I’m only speculating as I only saw the emergency vehicles outside so I cannot confirm what has happened.”
